I understand liquor and alcohol,  if used responsibly is ok, but, until you admit that alcohol is one of the worst, if not the worst legal substanc,  you can NOT schedule KRATOM or make it out to be anything bad! It is and will continue to save MANY more lives than it will negatively impact.  ONLY reason it is being looked at bad is because it is a direct threat to Big Pharma and the racket they control.  The thought of some “magical” plant coming along and derailing pills- the next worst thing to alcohol and actually helping people just drives the medical industry crazy! 
who ever is speaking of salmonella fails to realize that it is not the plant itself but either poor handling or the soil is was grown in is bad.   it can get it just like any other vegetable if not grown correctly or transferred properly.   The plant itself does not just produce it.  Not saying that is a good excuse and is ok but more info needs to be looked at case by case for the matter and not taking it all out on the plant as a WHOLE!
